Better implementation

Ok, first time I post here.
I want to write down my own imageboard program, just for the heck of it, and I am in a dilemma.
The way I had thought of it, I would have a single "content" file, that would be dynamic, and all the content would be generated within it.
However when I looked into futallaby for reference, the way they do it, is that there is no main "content" page, all pages are genereted within the script but are then dumped and delivered as static  html pages.
So, I want to axe you this question:
>Which way do you think its a better implementation?

>OP is a faggot

Ok, OP here again, let me know if my stupid head got it right:

If the content is delivered dynamically, that means that the server has to execute the script and access the database for every single visit to the board. Not so much of a strain for little to no traffic sites, but will certainly be if said site has a certain amount of traffic.

If, on the other hand, the content delivery is done via static html pages, the only times when the server will have to execute the scripts and access the database is when somebody actually posts, which, again, will certainly relieve the server if the site has high traffic, but won't make much difference for small sites.

Excuse my reek of noobishness, I just try to understand. You all begun from somewhere.
